- Qualifier TJ = TA DefinedPDF, 22 Kb, Archivo publicado: nov 3, 2010
In the header of most datasheet specification tables there is a qualifier for the tests defined in the table,(TA = TJ, unless otherwise stated). Specifically, these tests are valid for the device as long as the junctiontemperature remains within the specified limits for that device. - U-110 1.5 Mhz Current Mode IC Controlled 50-Watt Power SupplyPDF, 298 Kb, Archivo publicado: sept 5, 1999
The UC3825 family of PWM control ICs is optimized for high-frequency switched-mode power-supply applications. This application note describes the development of a 1.5 MHz current-mode IC-controlled 50W power supply. Push-pull topology is used for this DC-to-DC converter application of +48V input to +5V at 10A output. Increases in switching speed and dynamic performance are made possible by the U
